 * `peaks workspace migrate-1-4-1` — R004 subcommand.
 *
 * Cleanup helper for projects upgraded from 1.4.1 → 1.4.2. Moves per-session
 * files from the legacy `.peaks/_runtime/<sid>/<role>/<file>.md` path into the canonical
 * `.peaks/_runtime/<sid>/<role>/<file>.md` path. Default is dry-run; pass
 * `--apply` to actually `rename` the files and remove emptied legacy dirs.
